Its importance comes from the fast growing in several potential applications like robotics, medical surgery, manufacturing and complicated assembly systems which require the development of the Multi Degree Of Freedom (Multi-DOF) motors. The presented actuator design consists of a regular non-magnetic spherical rotor with impeded magnetic dihedral cones. Air core coils are carried on the internal surface of the spherical stator. The actuator design procedures are proposed, considering the optimal design parameters, to achieve the maximum output torque with specified position angles. According to the analytical magnetic field distribution, the actuator magnetic field is simulated and analyzed. The spherical motor torque model is studied to present the relationship between the motor coils input current set and the output equivalent targeted position. The torque and the coils input currents for different positions are derived. Both direct and inverse actuator models are simulated and connected together to produce a feedback system. The simulation and results of the developed spherical actuator are presented. It contains eight dihedral permanent magnets in the rotor and sixteen air core coils arranged into two eight groups around the equatorial line upper and lower.","PeriodicalId":247669,"journal":{"name":"2017 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131363336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For conventional converters, capacitor charge balancing is not a huge problem. Only the load ripple current flows through the DC link capacitor. Main load current doesn't affect the capacitor and it flows through the DC bus. For a MMC, charge balancing of all the module capacitors is a complicated task as the full load current flows through all the modules when MMC is operational. The module capacitors get charged and discharged very rapidly. Few charge balancing algorithms are already proposed in the literature. They have some disadvantages due to high execution time and complexity, as number of modules need to be inserted or bypassed is calculated in every step of operation. In this paper a simplified charge balancing algorithm is proposed depending upon the phase disposition modulation technique. In the proposed algorithm there is no need to calculate the number of modules that need to be inserted or bypassed during every step of operation. In addition, gate signals are given to the module switches directly. The new technique is fast and less complex. A nine level modular multilevel converter is simulated using the proposed algorithm in Matlab Simulink environment. All simulation results are presented in the paper.","PeriodicalId":247669,"journal":{"name":"2017 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132756880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commercially available options for space grade DC-DC converters operating in input range of 28–42V have limited features and performance in terms of EMI, PARD (Periodic and Random Deviation), output voltage lines, power, and efficiency. To enhance the power supply performance in payloads, an indigenous 24W isolated space qualified DC-DC converter with planar magnetics has been realized as a Hybrid Micro Circuit. Weight of the converter realized is 110 grams' and efficiency up to 80% across all loading conditions has been achieved. Design of converter incorporates critical safety features like inrush current limiter, over current and over voltage protection, which are required for high-reliability space borne applications. HMC has also successfully passed EMI tests as per MIL-STD-461E standards. This paper discusses the converter's technical aspects and challenges for realization along with achieved performance and comparison with existing space grade converters.","PeriodicalId":247669,"journal":{"name":"2017 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"476 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116027012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
